Nitrided D16 Welding Table for Enhanced Surface Hardness

• Ultra-high surface hardness: Working surface hardness exceeds HV550; repeated insertion and removal of fixture pins will not collapse the holes or cause indentations, ensuring long-term positional accuracy.
• Weld spatter resistance: Cooled weld slag does not fuse to the table surface and can be easily knocked off, reducing the workload associated with grinding and surface repair.
• Wear, corrosion, and rust resistance: Unlike painting or black oxide finishing, nitriding is a metallurgical heat treatment process rather than a coating; it will not peel or flake off, withstands humid workshop environments, and extends service life by 3-5 times.
• Toughness of the base material: Only the surface layer is hardened, while the internal base material retains its toughness; the unit will not crack or shatter under impact, unlike components that are through-hardened (which are prone to brittle fracture).
• Five-sided usability: The top surface and all four sides are CNC-milled and nitrided, allowing for fixture clamping and positioning in X, Y, and Z dimensions; this eliminates the need to repeatedly fabricate specialized welding jigs, significantly reducing tooling costs.

• Monthly: Clean welding slag and dust from the holes using a nylon or copper brush (do not use a steel wire brush); check the insertion and removal status of the pins.
• Quarterly: Calibrate the bracket level, tighten bracket bolts, and re-verify the flatness of the welding table surface.
• Annually: Re-measure hole spacing and verticality; re-verify overall precision.

This US end-user has been using our nitrided welding table in his workshop. He is so satisfied with the table's real-world performance that he plans to sell his current unit and place a new order with us. He also intends to purchase additional matching tooling accessories and prefers direct home delivery instead of bulky freight import. This genuine feedback reflects the solid quality and reliability of our 3D modular welding tables for workshop fabrication.
